The Forest Preserve District of DuPage County will conduct a bioblitz, counting the species in a 3500-acre area spanning 4 contiguous preserves, on June 26-27, 2015. The bioblitz will include both scientist and citizen science teams. Updated species counts will be posted in a public exhibit area, which also will be the base for other presentations and activities related to biodiversity. Data from the bioblitz will augment and update the District's ecological database, accessible to the public through the Observe Your Preserve website.
